When using -Wimplicit-fallthrough in our CFLAGS, the compiler showed warning: target/ppc/mmu_helper.c: In function ‘dump_mmu’: target/ppc/mmu_helper.c:1351:12: warning: this statement may fall through [-Wimplicit-fallthrough=] 1351 | if (ppc64_v3_radix(env_archcpu(env))) { | ^ target/ppc/mmu_helper.c:1358:5: note: here 1358 | default: | ^~~~~~~ Use "qemu_log_mask(LOG_UNIMP**)" instead of the TODO comment. And add the break statement to fix it.
